High-performance chloride-free liquid concrete antifreeze admixture by Havash. Designed for cold-weather concreting, accelerating setting time, enhancing early strength development, and providing plasticizing action without corroding rebar.
Havash Chloride-Free Concrete Antifreeze – Ultimate Winter Concreting Protection
Havash Chloride-Free Concrete Antifreeze is a specialized liquid admixture formulated for concreting and cementitious mortars in freezing temperatures and cold weather conditions. Free from chloride ions, it guarantees absolute protection against structural rebar corrosion while depressing the freezing point of mixing water and promoting rapid hydration and early compressive strength.
100% Chloride-Free: Completely safe for reinforced concrete; causes no corrosion to steel rebar.
Accelerated Hydration & Setting: Significantly reduces setting times and boosts early age strength.
Plasticizing Effect: Enhances workability while allowing a reduction in the water-to-cement ratio.
Freezing Point Depression: Prevents frost damage to fresh concrete at sub-zero temperatures.
Easy Dispersion: Mixes rapidly and uniformly into the concrete batch.
| Ambient Temperature (°C) | Dosage Rate (% of Cement Weight) |
| 0°C to -5°C | 1% – 2% |
| -5°C to -10°C | 2% – 3% |
| -10°C to -15°C | 3% – 5% |
Measure the calculated dosage of antifreeze and mix it thoroughly into the gauging/mixing water.
Do not add the admixture directly to dry cement.
For best results, add to the transit mixer near the end of batching and mix at high speed for 3 to 5 minutes.
Storage: Store in original sealed containers in a cool, covered area away from direct sunlight at temperatures between 5°C and 35°C.
Safety: Wear protective gloves and safety goggles during handling. In case of contact with eyes, rinse immediately with plenty of clean water.
